LIFT TRUCK REQUIREMENTS
CAPACITY
CLAMP HYDRAULICS
Capacity shown on the Clamp name plate is for the
Clamp only. The combined truck and Clamp
capacity is provided by the lift truck manufacturer.
Recommended Truck Pressure: 2300 to 2500 PSI
(159 to 170 bar)
Hydraulic fluid: petroleum based hydraulic fluid
only
Hydraulic supply group: includes hoses and
take-up - one set for each function
Auxiliary valve:
2 Function (Side Shift & Clamp) = a double auxiliary
valve
Oil Volume Settings:
Side Shift = 3 GPM
Clamp Open/Close = 7 GPM
GENERAL INSTALLATION PROCEDURES
1. Make sure that the attachment centering lug is completely seated in truck carriage center notch.
2. Clearance between the lower retainers that hold the attachment to the truck lower carriage bar should
be as shown below.
.13" (3.2mm) MAXIMUM
TRUCK LOWER CARRIAGE BAR
LOWER RETAINER
3. Attach truck supply group (take-up) to clamp valve on attachment base.
4. Standing clear of the Clamp attachment cycle the attachment in and out several times. Use caution
because partially filled hydraulic lines may cause erratic movement.
GENERAL INSPECTION AND MAINTENANCE
1.
Check all hydraulic fittings, hoses, cylinders and valves for leakages - repair or replace as required
2.
Check bladder/water pressure. If out of operating range adjust as required using Loron Hand
Pump #112909. Check clamp force and adjust. (See page 12.)
3.
Time Schedule: Check pressure and clamp forces every 3 weeks.
Water pressure = 4-6 psi
Clamp Force = 1600lbs
4.
All bolts should be checked and tightened as required.
5.
Check lower retainer clearance - see item 2 in General Installation Procedures above.

CYLINDER SERVICE
Prior to assembly lubricate seals, cylinder bore and rod with STP.
Inspect all parts for scratches, nicks and gouges- -replace all damaged components.
Inspect cylinder bore and rod for scoring- -replace if scored
Avoid damage to seal grooves- -use a dull screwdriver for seal removal
Torque piston nut to 110 FT/LBS. (15.3 kg-m)

CLAMP ADJUSTMENTS
CLAMP FORCE CHECK/ADJUSTMENT
OPEN FORCE CHECK/ADJUSTMENT
1) Check water pressure. If out of operating range
fill with Loron hand pump #112909.
Note: when operating in below freezing
temperatures us RV antifreeze in place of water.
Open the arms against a force fixture and adjust for
desired maximum force.
2) Check the clamp force centered on lower pad
1) Clamp on the heaviest load that will be handled
2) Adjust the side shift force down until the arms
stop
3) Turn the adjusting screw one turn in.

ARM SLIDE & SHIM REPLACEMENT
1.
To replace the slides extend the arms to the fully open position. Release system pressure prior to removing the arms by
turning the truck off and working the side shift and clamp function controls several times.
2.
Support the arm with an overhead crane or lift truck. Be sure to secure the chain or sling in a manner that prevents the arm
from falling out of the chain or sling when hanging free of the clamp frame.
3.
Remove the cotter pin, slotted nut and spherical bearing from the end of the clamp cylinder rod. Keeping hands and feet
clear, carefully slide the clamp arm off of the clamp frame.
4.
Install the arm on the clamp frame ensuring that the arm moves freely without excessive binding. If the arm is too loose or
too tight add or remove shims as required. Once the clearance is satisfactory insert the cylinder rod into the cylinder anchor
on the arm. Install the spherical bearing, nut and cotter pin onto the cylinder rod end. Be sure to leave .03" - .06" (.7mm to
1.5mm) clearance to allow the cylinder to "float" on it's mountings (see page 11).Remove the cotter pin, slotted nut and
spherical bearing from the end of the clamp cylinder rod. Keeping hands and feet clear, carefully slide the clamp arm off of
the clamp frame.
BLOCK:

FOR L35 CLAMP MODELS
2.25" X 2.25" X 3" LONG
(57.2mm X 57.2mm X 76mm)
ARM
CLAMP FRAME ARM BAR
5.
Inspect slides and slide buttons for wear. Slides may be rotated end-for-end and re-used if excessively worn on the outer
end only. Extra shims may be used to tighten operating clearance on slightly worn slides. Replace any slides worn to less
than .06" (1.5mm) thick or any slide that is deeply scored or broken.
6.
To aid in replacing the slides a block may be fashioned of wood or another convenient material to the dimensions shown
above. The block is inserted in the end of the arm to hold the slides, shims and buttons in position while the arm is inserted
over the arm bars on the clamp frame. The block is expelled out the opposite end of the arm as the arm is pushed onto the
frame.
7.
Prior to installing the arm the block may be used to determine the number of shims to place under the slides. Adjust the
clearance between the slides and the block to provide approximately .06" (1.5mm) running clearance between the slides and
arm when installed.

TROUBLE SHOOTING GUIDE
LOADS SLIPPING OR DROPPING
POSSIBLE CAUSES
SOLUTIONS
1.
Clamp force set too low
1.
Adjust clamp force page 12
2.
Internal leakage in cylinder.
2.
Replace cylinder seals. If tube, piston or rod is scored
replace with new parts.
3.
Load too heavy for the clamp capacity
3.
Consult factory.
4.
Load my not by stacked correctly or may need to be
unitized
4.
Restack or unitize load (shrink wrap)
5.
Bent arms or contact pads
5.
Consult factory.
6.
Damaged / leaking hydraulic hose
6.
Replace damaged hose
CRUSHING LOADS
POSSIBLE CAUSES
SOLUTIONS
1.
Clamp force set too high
1.
Adjusting clamp force, page 12
2.
Bent arms or contact pads
2.
Consult factory
3.
Leak in bladder system
3.
Check for leaks and repair.
ARM CHATTERING OR ERRATIC MOVEMENT
POSSIBLE CAUSES
SOLUTIONS
1.
Bent clamp arms
1.
Consult factory
2.
Nylon slides sticking
Note: Sticking slides can cause inconsistent clamp
force measurements
2.
Clean slides if necessary, the slides are self lubricating.
3.
Nylon slides worn, broken or missing.
3.
Replace damaged slides, shims and retaining buttons.
